Can the Bay Area grow in population and be sustainable?

In 1968, biologist Paul Ehrlich wrote the best-seller "The Population Bomb," warning of mass starvation in the face of uncontrolled human population growth.

Taken as alarmist at the time, the book nevertheless started a debate about the world’s limited natural resources and the human race’s voracious appetite. Of course, we didn’t all starve, thanks in part to advancements in agriculture. But more than 40 years later, with the doubling of the world’s population, we’re faced with a different doom-and-gloom scenario: climate change. Ehrlich, now a population studies expert at Stanford University, hasn’t backed down.
